TAPELESS SHEET-CONVEYER MECHANISM FOR PAPER-FOLDING MACHINES.

EPECIPICATION forming-part of Letters Patent i\To. 355,353, dated January 4, 1857.

Application filed January 8, 1886. Serial No. 188,042. (No model.)

to the letters of reference marked thereon, forming part of this specification.

My invention relates to sheet conveying mechanism for paper-folding machines; and it consists in the improvements hereinafter set forth and explained.

My invention is illustrated in the accompa- 20 nying drawing, in which the figure is a top or plan ,view of a paper-folding machine embodying my improvements.

In its general construction the folding-niachine shown contains the features usually embodied in paper-folding machines of ordinary construction, the sheet being conveyed to the first set of rolls, A A, by means of ordinary conveyer-tapes B. For conveying the oncefolded sheet to the second set of rolls, D D,

01 dispense with the carrier-tapes ordinarily 5 it is received upon the spiral rolls (J O and used, and use spirally-fluted conveyor-rollers O, which are placed in the'machine obliquely to the rolls D D, so that as the once-folded sheet leaves the first set of folding-rolls, A A,

carried to its proper place over the second set of rolls. The spiral flutes on the rolls acting upon the sheet on lines parallel with the folding-rolls D D, and the rolls 0 being located sheet cannot sag down between them. These oblique rolls are driven by means of shafts E along the sides of the folding-machine, (one of which, however, not being shown.) Onthe shafts E are beveled gears F,which intermesh with beveled gears G on the journals of the I rollers C. However, the rollers C may be driven in any suitable and convenient manner.

For convenience, in the drawing I have shown but one set of spirally-fiuted oblique conveyer-rolls in the machine but these sheetoonveyingrolls are equally applicable to any or all of the folding-rolls of the machine, so that there need be no carrier-tapes used on the machine, spirally-fluted conveyer-rolls being used in their stead.

Having thus described my invention so as to enable others skilled in the art to which it appertains to construct and use the same,what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a paper folding machine, the combination, with folding-rolls of said machine, of spirally-fluted sheet-conveying rollers placed obliquely to such folding-rolls, substantially as set forth.

2. In combination with the folding-rolls of a paper-folding machine, a tapeless sheet-con- Veyer mechanism consisting of spirally-fluted rollers placed at an angle of substantially fortyfive. degrees to the folding-rolls of said machine, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
